[Gluster-users] Issues with Geo-replication (GlusterFS 6.3 on Ubuntu 18.04)

[Alexander Iliev]

Hi Sunny,

Thank you for the quick response.

It's not clear to me however if the fix has been already released or not.

The bug status is CLOSED NEXTRELEASE and according to [1] the 
NEXTRELEASE resolution means that the fix will be included in the next 
supported release. The bug is logged against the mainline version 
though, so I'm not sure what this means exactly.

 From the 6.4[2] and 6.5[3] release notes it seems it hasn't been 
released yet.

Ideally I would not like to patch my systems locally, so if you have an 
ETA on when this will be out officially I would really appreciate it.

Thank you!

Best regards,
